摘　　要：介绍了一种基于PCIE总线主模式DMA高速数据传输系统的设计。该系统利用Xilinx公司V5系列的FPGA芯片搭建了x1通道的PCIE系统。实验利用自行开发的PCIE接口板实现了单字读写及DMA读写的传输方式,并在上位机软件界面上及Chip Scope中显示并验证了读写数据的正确性,经实验表明传输速率可稳定在400 MB/s左右。This paper presented a high speed data transmission system based on PCIE bus master DMA mode. An xl channel PCIE system was set up using the FPGA chip from V5 series products produced by Xilinx company. Several transmission manners, such as single word reading and writing, DMA reading and writing were realized by the PCIE interface board, which was developed independently. The data can be displayed via GUI on host computers and chipscope, which can also be used to validate the correctness of the data. Experimental results show that the data transfer speed can be stable at around 400 MB/s.
